MANUFACTURE OF EYELETS AND THE LIKE.

Specification of Letters Patent.

Patented Sept. 19, 1905.

2'0 aZZ whom it may concern.-

Be it known that I, WILLIAM GARDINER MURPHY, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in the Manufacture of Eyelets and the Like, of which the following is a specification.

This invention relates to methods of making eyelets, hollow rivets, and the like employed either for securing fabrics or plies of material together or for securing an article to a fabric, and the present application is a division of my pending application, Serial No.

243,820, filed February 2, 1905, wherein the article or product is claimed.

In all forms of eyelets and hollow rivets the shank or body is passed through a hole in the material, and the portion which extends out beyond the material is spread and then clenched or riveted down on the material in the form of a flange. As such securing de; vices are usually made from metal, this spreading of the tube and flattening into a flange with its plane at right angles to the axis of the eyelet is apt to split the metal and give it a ragged and unsightly appearance, and this weakens its hold on the material. For this reason in some constructions great care is taken and considerable expense resorted to in order to conceal the clench of the rivet.

The object of-the present invention is to provide a fastening device of this character wherein that portion of the tubular body which is to be spread and laid flat in the clenching is longitudinally folded in the manufacture of the eyelet or rivet, so that enough metal will be supplied to form the flattened flange without putting undue strain on the metal. Thereby the clenched end of the eye let will present a complete and perfect retaining-flange and also one having an ornamental Referring primarily to Figs. 1 to 3, Fig. 1v shows the eyelet drawn to its primary shape by suitable dies. The body a is tubular and is herein shown as provided at one end with a head-flange 6, although this flange is not essential to the present invention and may be omitted or varied in form and size to suit requirements. At the other end (the lower end as seen in Fig. 1) is formed another flange 0.

The second shape or stageof the eyelet is illustrated inFig. 2, wherein it will be seen that the flange c, which is destined to be the clenching-flange, is drawn into a conical shape by forming in it folds which take up the surplus metal.

The final or finished shapeor stage is illustrated in Fig. 3, wherein it will be seen that the flange 0 has been brought into a substantially cylindrical form by folding the metal more closely and bringing this portion into line with the shank or body a. This is the form the eyelet has when sold to the trade.

It will be understood that With suitable dies in the factory there will be no difliculty in forming the flange c primarily; but in the use of the article it is not easy to perfectly spread and clench down the tubular extremity of the ordinary form of eyelet; but formingv folds in the flange and bringing it to a tubular form there will be no difliculty in effecting this.

The invention is well adapted for a grommet, which is a form of eyelet used in tents, awnings, and the like.

Having thus described my invention, I claim The herein-described method of making an eyelet, which consists in primarily forming a clenching-flange on the eyelet-body, then forming tapered, radially-extending, fan-like folds in said flange to take up the surplus presence of two subscribing witnesses.
